I've never seen an option to control that setting. If it changed after inserting an inventor file, I'd try to insert a native solidworks file next. Maybe it will automatically switch back?
Regarding inventor files:
I imported one the other night and found my system was really slow when applying new features to it. If possible, I'd break any association links with the original file, or simply re-import the model as a dumb solid. I can't think of any benefit that could make up for how slow everything became.
